Application fil ed March 13, 1916.- Serial No. 83,773.

To all whom it may concern:

Be it known that I, WALTER'J. ELLIS, a citizen of Canada, anda resident of Vancouver, in the Province of British Columbia, have invented certain new and useful Improvements in Processes of Embossing,'of which the fellowing is a full, true, and exact specification.

My invention relates to processes of embossing designs and the like upon paper and the like. One of the principal objects of my invention is to furnish a cheap and efficient process of preparing an embossing die for the press to provide a die which .is adaptable for use in an ordinary letter head printing press which operates much more rapidly than. an embossing press.

My process consists in marking or laying out the outline of the design or die in any suitable material, preferably on a smooth and dense bristol board; cutting the die with appropriate cutting tools along theroutline, thereby forming male and female dies simultaneously, placing the cut dies in their interlocked position, within a hinged or folded member of relatively flexible material, pasting or otherwise securely fastening one side of the male die to one. side of the hinged member and the opposite side of the female die to the other side of the hinged member. By opening the folded or hinged member about its hinged point, it allows of a proof sheet being inserted between the male and female dies and when closed and pressed together, will produce an embossed proof. The dies or rather the hinged backing member are mounted upon type base plates ready for the press. The hinge is severed by a sharp knife as the dies are now in secure positions.

My process may be better understood by referring to the drawings in which Figure 1 is a plan view of a simple die. 'Fig. 2 is a central cross section of same. Fig. 3 is a similar view of Fig. 1 of compound die. Fig. 4 is a cross-sectional view of Fig. 3.

Referring more uarticularly to the draw-' ings, numeral 1 in icates a backing member which is hinged as at 2. The male die 3' is shown secured to one half of the hinged member and a female die 4 is secured to the vious case. In making a compound die, the

top and'base portions are cut as previously described and the base dies are first secured tothe backing member, the top dies are next centered and secured to the base dies.

What I claim is 1. The process of making embossing dies by drawing the design'outline of male and female dies upon a relatively hard but easily cut material, cutting thesaid male and female dies apart along the said outlines, placing the said male and female dies between adjacent faces of a hinged and relatively flexible backin member, securing one side of the male die to the backing member on one side of the hinge, securing the opposite side of thefemale die to the opposite side of the said backing member respectively, securing the opposite sides of said backing member to type bases, and when said dies are in an interlocked position, severing the said hinge.

2. The process of making embossing dies by drawing the design outline of male and female dies upon a relatively hard but easily cut material, cutting the said male and female dies apart along the said outli.nes,'-placing the said male and female dies between adjacent faces of a hinged and relatively flexible backing member, said dies being in an interlocked relation toeach other, securing one side of the male die to the backing member on one side of the hinge, securing the opposite side of the female die to the opposite side of the said backing member respectively, securing the opposite sides of Patented Apr. 24, 1917.

said backing member to type bases, and

when said dies are in an interlocked posi tion, severing the said hlnge.
